8. The location server of claim 7 , wherein each of the first assistance information representing assistance data for the first NSS and the second assistance information representing assistance data for the second NSS, further comprises at least one of the following elements: a differential correction, a navigation model, an almanac, acquisition assistance, or real-time integrity information.
9. The location server of claim 7 , wherein each of the first assistance information representing assistance data for the first NSS and the second assistance information representing assistance data for the second NSS, further comprises a GPS-Galileo time offset (GGTO).
10. The location server of claim 9 , wherein the GGTO is included in the first assistance information and the second assistance information in response to the location server maintaining a Galileo system time distinct from a GPS system time.
11. The location server of claim 7 , wherein the first method information representing positioning methods for the first NSS comprises positioning methods of a global position-satellite (GPS) system, and wherein the second method information representing positioning methods for the second NSS comprises positioning methods of a Galileo satellite system.
12. The location server of claim 7 , wherein the processor is further adapted to calculate a time offset representing a conversion from time dependent assistance data for the first NSS to, time dependent assistance data for the second NSS.
13. A computer program product, comprising: a non-transitory computer-readable medium comprising: code to cause at least a location server to compile a measure position request message, wherein the measure position request message comprises first method information representing positioning methods for a first navigation satellite system (NSS); second method information representing positioning methods for a second NSS and corresponding to the positioning methods for the first NSS; first assistance information representing assistance data for the first NSS; and second assistance information representing assistance data for the second NSS and corresponding to the assistance data for the first NSS; and code to cause at least the location server to transmit the measure position request message to a mobile station.
14. The product of claim 13 , wherein each of the first assistance information representing assistance data for the first NSS and the second assistance information representing assistance data for the second NSS, further comprises at least one of the following elements: a differential correction, a navigation model, an almanac, acquisition assistance, or real-time integrity information.
15. The product of claim 13 , wherein each of the first assistance, information representing assistance data for the first NSS and the second assistance information representing assistance data for the second NSS, further comprises a GPS-Galileo time offset (GGTO).
16. The product of claim 15 , wherein the GGTO is included in the first assistance information and the second assistance information in response to the location server maintaining a Galileo system time distinct from a GPS system time.
17. The product of claim 13 , wherein the first method information representing positioning methods for the first NSS comprises positioning methods of a global position satellite (GPS) system, and wherein the second method information representing positioning methods for the second NSS comprises positioning methods of a Galileo satellite system.
